There are different grades specified within both electrode types, such as:
· HP - High Power
· HD - High Density
· UHP - Ultra High Power
· SHP - Super High Power
Graphite electrodes are mainly used in electric arc furnace. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in EAF. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes. Graphite electrodes are divided into 4 Types: RP Graphite electrodes, HP Graphite electrodes, SHP Graphite electrodes, UHP Graphite electrodes.
